Improvement in mangles



UNITED STATES HENRY TREGELLAS, OF CALUMET, MICHIGAN.

IMPROVEMENT IN MANGLES.

Specification forming part of Letters Patent No. 118,654, dated August29, 1871.

To all whom it may concern:

Be it known that I, HENRY TREGELLAS, of Calumet, in the county ofHoughton and State of Michigan, have invented a new and valuableImprovement in M an gles; and I do hereby declare that the following isa full, clear, and exact description of the construction and operationof the same, reference being bad to the annexed drawing making a part ofthis specification, and to the letters and figures of reference markedthereon.

Figure l of the drawing is a top view of my invention. Fig. 2 is acentral vertical longitudinal section through the line as This inventionhas relation to machines for ironing or smoothing cloth, clothes, andthe like, known as mangles or calender-s; and it consists in an improveddevice for that purpose, simple in construction, easily managed, andeffectual in operation.

A and A represent corresponding inclined end legs of the frame. Theselegs are crossed by like corresponding legs at a and a, and the fourlegs are braced by end braces b, I) b, and b, and by longitudinal bracesc and c. This frame supports a floor, G, as shown, and the wholesupports the machinery and the goods to be smoothed at a convenientheight. D and D represent end blocks, shaped, as shown, for adaptationto pressure upon the middle portion of the springs d and d,respectively. These blocks are connected at the ends by side pieces 0and c, keyed together, as shown, and the whole forms an upper frameresting upon the lower frame, and connected to it by clips attached tothe under side of the end blocks. F and F are smooth-faced rollers ofequal size, placed on opposite sides of a smaller roller, F. Theserollers are supported in bearings f, f, and f, within the upper frame,and on the lower frame, as represented, the bearings for the larger andouter rollers being so formed that the rollers may be easily taken out,as at 9, that the material to be smoothed may be easily wound on them.These bearings are connected to the lower frame by clips and to the endsof the springs (Z and d by links, so as to move backward and forward asthe spring d or the upper frame is moved, the side piece 6 being slottedat e to allow of such motion ofthe frame. Rubber blocks or springs h, h,It", and h, are placed between the ends of the journal-boxes and theends of the springs to afford a yielding motion to the rollers onaccount of irregularities in the material formed by folds and the like,and the spring at is provided with a screw, H, having bearings in theend block D and on the lower frame, and a wheel-head for the purpose oftightening and loosening the rollers, as occasion may require. By theaid of stops 1' and t" on the lower frame the screw operates with likeforce on both of the large rollers. The

central roller F is operated by means of the cogwheel K on its journal,pinion-wheel k on the shaft k, and crank-wheel L, all as shown. Theroller F may be covered with some suitable material, as canvas, toprevent slipping. Motion is communicated from the roller F to therollers F and F.

I claim as my invention- 1. In a mangle, the combination, with the fixedcentral roller F, of the slotted adjustable frame D c D c, screw H,springs d d, and side rollers F F, substantially as specified.

2. In a mangle, the combination, with the sliding journal-seats f f, ofthe transverse spring d and the rubber cushions h h, substantially asand for the purpose described.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.
